Offering greater air flow potential for ever bigger power gains, this intake manifold has been accepted by NASCAR for use in the Grand National West/Grand National East series. The carb mount pad is 1.12" taller than the Victor Jr. LS1, and the port exits have been increased to 1.08" x 2.74". Edelbrock offers the optional LS1 Timing Control Module #91238 to drive the stock LS1 Coil-on-Plug ignition system. LS2 applications require MSD's #6012 LS2 ignition controller (available through MSD Performance). Super Victor EFI LS1/LS2 manifold #28095 is for high-output competition EFI systems and features machined injector bosses. It's compatible with either our #3878 4V throttle body series or any of our square-bore EFI elbows.
